Abstract

A medical implant delivery system maintains an orientation between a guidewire lumen of an inner member of the system and a rapid-exchange port in an outer member. The medical device is disposed intermediate the inner and outer members and in friction or pressure-fit contact with the outer member. Once the guidewire lumen of the inner member and the rapid exchange port of the outer member are oriented, the friction or pressure-fit operates to maintain the orientation until deployment of the medical implant. Orientation is further maintained by a telescoping coupling of the guide wire lumen with the rapid exchange port.

RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application Ser. No. 60 / 680,400, filed May 12, 2005 by Khamla Vongphakdy and Huisun Wang, and U.S. Provisional Patent Application Ser. No. 60 / 680,791, filed May 13, 2005 by Khamla Vongphakdy and Huisun Wang, the entire subject matters of which are hereby incorporated by reference.FIELD OF THE INVENTION

[0002] The present invention pertains to a system for delivering an implant to a site in a body lumen. More particularly, this invention pertains to a rapid exchange-type delivery system for a self-expandable implant such as a stent. BACKGROUND OF THE INVENTION

[0003] Stents are widely used for supporting a lumen structure in a patient's body. For example, a stent may be used to maintain patency of a coronary artery, other blood vessel or other body lumen. One or more stents may be placed in a vascular or non-vascular passage or conduit such as an artery, vein, graft, ureter, urethra, bronchus, eso...
